Maintaining a clean, organized work area and controlling how people and materials move through it is essential to limit how contamination spreads. Regular cleaning reduces surface contamination, using designated containers keeps waste and materials separate to prevent cross‑contamination, controlling traffic minimizes opportunities for contaminants to be carried between areas, sealed waste containers prevent leaks and exposure, prompt spill cleanup stops contaminants from spreading, and routine surface surveys help verify cleanliness and identify hotspots. This approach targets the main pathways contaminants use: surfaces, waste handling, movement, and ongoing monitoring. Other practices fall short because sporadic cleaning and random waste disposal allow buildup, signs alone do not remove contaminants, and rearranging equipment without a cleaning plan can create new contamination paths.
